Specialized for Hard Rock Conditions in Mining Picks

What is the secret behind Duerbot picks helping to improve coal mining efficiency?

In the coal mining industry, "efficiency" is an unavoidable core topic—progressing a bit faster and reducing downtime can significantly boost overall benefits. As the "teeth" of tunneling and coal mining equipment, the performance of picks directly affects the mining pace. Duerbot picks stand out in enhancing coal mining efficiency not by chance but through several practical "secrets," which we will discuss in detail today.

Secret 1: Duerbot picks are wear-resistant and durable, reducing the frequency of downtime for replacement

For coal mines, nothing hampers efficiency more than frequent stops to replace picks. Many coal mines previously used picks that wore out quickly, with blades dulling or pick bodies deforming, requiring two to three replacements per shift. This repeatedly cut into effective operational time.

Duerbot picks excel in wear resistance, using high-hardness alloy materials and optimizing the brazing process between the pick head and body to withstand friction and impact in coal seams. A coal mine in Henan reported that using Duerbot U135 picks with Sany tunneling equipment showed no significant wear after a full shift, eliminating mid-shutdown replacements. The tunneling machine operated continuously, increasing shift progress by nearly 20%. With fewer stoppages, efficiency naturally improved.

Secret 2: Duerbot picks adapt to multiple working conditions, delivering stable performance even in complex environments

Coal mining conditions are never one-size-fits-all—some coal seams mix with hard rock, some are soft and prone to collapse, and others contain many impurities with complex structures. Without tailored design, picks either fail to cut or break easily, making efficiency gains impossible.

Duerbot picks are specifically optimized for different conditions: for seams with high hard rock content, the pick head alloy layer is thickened to withstand impact and crush rock effortlessly; for soft coal seams, the chip flute design is improved to reduce coal dust clogging and ensure smoother cutting. A coal mine in Shanxi previously used standard picks in soft coal seams, frequently experiencing jams due to poor chip removal. After switching to Duerbot’s adapted picks, jams decreased, and coal output per shift increased by 30%. Workers noted that "operations became much smoother."

Secret 3: Duerbot picks come with on-site service, promptly resolving usage issues

Coal mining operations are fast-paced, and if pick-related problems arise without timely support, progress can easily be delayed. Many mines worry that "once picks are purchased, there’s no follow-up," but with Duerbot picks, this concern is eliminated.

Whenever a coal mine has needs, Duerbot engineers make special trips to the site—during initial use, they assist with installation checks and cutting parameter adjustments; during subsequent operations, they provide quick responses via phone or video for any questions, and revisit if necessary. When a coal mine in Shandong first used Duerbot picks, workers were unfamiliar with operational details. An engineer arrived the same day, identified abnormal wear due to incorrect cutting angles, and provided a solution. With such on-site support, mines can focus more on mining progress without worrying about pick usage issues.

For coal mines, choosing the right picks means selecting the right "efficiency partner." Duerbot picks avoid flashy marketing but instead address the pain points of "frequent downtime, poor adaptability, and lack of support" in coal mining through tangible improvements in wear resistance, adaptability, and service. It is for these reasons that more and more coal mines are choosing Duerbot picks, making them a "reliable partner" in boosting mining efficiency.
